In contrast, conservation <br /> can only be accomplished within an ecosystem concept. It is therefore critical <br /> that ecological aspects of management prevail in endangered species <br /> management: an understanding of facors limiting the distribution and abundancE <br /> of the target animal must be well understood and incorporated into any <br />management attempt! <br />Preceeding sections have discussed the life cycle and ecology of the fish <br />as background for management. The following summarizes my interpretation of <br />important management activities to date, and provides recommendations for <br />19 <br />
